SPECIFICATION forming part of Letters Patent No. 497,829, dated May 23,1893. Application Iiled October l0, 1892. Serial No. 448,373. (Nomodel.)

T all whom t may concern:

Be it known that I, THOMAS K. SHEA, a citizen of the United States,residing at Cincinnati, in the county of IIamilton and State of Ohio,have invented certain new and useful Improvements in Cars; and I dodeclare the following to be a full, clear, and exact descrip tion of theinvention, such as will enable others skilled in the art to whichappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to improvements in cars for streetrailway andsimilar purposes and the object is to support and carry the body of suchcars in a new manner whereby its jolting and jarring is greatly lessenedand they are caused to ride more easy on their wheels or trucks andafford greater comfort to the passengers therein. This is substantiallyaccomplished by interposing additional springs between the running gearor trucks and the body and by disposing the former near the top of thebody which latter is swung or hung on these springs.

In the following specification is found a full description of myinvention, the same being also particularly pointed out in the claims atthe end thereof and its construction illustrated in the accompanyingdrawings, in which- Figure 1, is a side-elevation of a car provided withmy improvements, parts of one of its sides broken out. Fig. 2, is avertical crosssection of the same, the plane of said section passingthrough a line fyy on the near side of the car and through a line oc-xon the far side of the car. Fig. 3, is a perspective view of a part ofthe frame which supports the car-body, showing the springs connected ina modified manner.

6, are suitable wheels secured upon axles 7, which carry bearings orboxes 8, at their outer ends. Braces 9, secure these boxes to a rail 10,which connects all the wheels or trucks.

11, are customary springs resting on the trucks and supporting thesuper-structure of the car in the well known manner.

I do not limit myself to the construction of the trucks as describedthus far and desire the same to be regarded merely as a type for manyothers which are adaptable for this purpose.

Supported by truck-sprin gs 11, are uprights 5 5 12, held in positionthereon in any suitable manner but preferably as shown, which is bypassing them loosely through a slot in rail 10, and by providing thexnwith a base 13, which t-s over boxes S. free to vert-ical vibration andadjustment on springs 11.

14, is an oblong frame, corresponding substantially in its dimensionswith the length and width of the car and 12, to which it is rigidlysecured. This frame sustains the roof of the car and also the top of thesides which consist of an inner and outer casing 15, and 1G,respectively.

17, are rods extending downwardly frame 14, and are provided at theirlower ends with round plates 1S, which form rests for coil-springs 19.20, are other plates resting on top of these springs and connected tothe Thus said uprights are 6o from 7o bifurcated ends of rods 2l, whichsupport 75 the floor-sills 22. These sills support the door 23, of thecar and also the lower part of the sides which consist of an innercasing 24, and an outer one 25, which with their upper ends reachbetween casings frame 14.

It will be observed that all jars and jolts to which the wheels aresubject will pass through the modifying action of two springs 15, and16, affixed to 8o before reaching that part of the car which di- 8 5rectly supports the passengers. Whatever of the jarring motion of thewheels is notbroken by springs 11, before it reaches uprights 12, willbe almost neutralized by springs 19, be-

fore it reaches the lower part of the car which 9o hangs on these lattersprings. During these vibrations the lower part of the car swingsindependently on the upper part and the lower part of the sides 24., 25,slide or telescope resting on uprights""6`5` within the upper part 15,1G, so that at all 95 y,

times the sides of the body are completely connected and closed.

In Fig. 3. the skeleton or frame which supports the two parts of the caris shown. Ob-

long frame 14, is the part which sustains the roo top and upper parts15, 16, of the sides and rods 21, and sills 22, are the parts which sup-Y.the omission of port the car-floor and the lower parts 24, 25, of thesides. The inner part or casing24, passes to and meets floor 23, whilethe outer part 25, for the sake of better appearance passes pref-Verably below the floor-sills 22, so as to cover their ends. In thislatter figure theeonnection of the springs 19, has been modified by thespring-rests 18, and 20, and the two ends of the springs connectdirectly to rods 17, and 21, or to trame 14, and rods 21. Y

Having explained my invention, Irclaim as new- 1. An improvedconstruction for cars, oonsistingof the combination of wheels or trucks,uprights restilng thereon, an independent upper part ofthe car supportedon these uprights, and consisting of the oar root and upper parts ofsides an independent lower part of the car, consisting of floor andlower parts of sides elastic or spring-supports interposed between upperand lower parts for sustaining these lower parts, the two parts of thecar slidingr or telescoping within each other, all as substantiallyshown and described.

2. An improved construction for cars, consisting ot' the combination ofwheels or trucks, uprights resting thereon, a frame 14, snpported bythem, an independent upper part of the car resting on said frame, rodsor supports which sustain an independent lower part of the car and thefloor of the same and springs interposed between the two parts of thecar, all as substantially shown and described.

3. An improved construction for cars, consisting of the combination ot'wheels or trucks,

uprights resting thereon, a frame 14, supported by them, an independentupper part of the car resting on said frame, rods 17, and 21, secured toframe 14, an independent lower part of the car supported by said rodsand springs interposed between these rods, all as substantially shownand described.

4. An improved construction for cars, consistingof the combination ofwheels ortrucks, uprights resting thereon, a frame 14, supported bythem, an independent upper part of the car resting on said frame, rods17, having rests 18, depending from said frame, springs 19, supported onrods 17, bifurcated rods 21, having a rest 20, which rests on springs19, and an independent lower part of the car including its Hoor,supported by rods 21, all as substantially shown and'described.

5. An improved construction for cars, consisting of the combination ofwheels or trucks, uprights resting on them,a frame 14, resting on theseuprights and having secured to it the upper part of the sides of the carwhich consist of a double casing 15, 16, elastic supports depending fromframe 14, an independent lower part of the sides sustained by saidsupports and also consisting of a double oasing 24, 25, which inconjunction with the upper part of the sides incloses and hides allparts of the frame and construction, all as substantially shown anddescribed.

6. An improved construction for cars, oonsistingot` the combination ofwheels or trucks, rails 10, connecting them, springs 11, resting on thetrucks, uprights 12, supported on springs 11, and guided by rails 10, anindependent upper part of the car resting on uprights 12, an independentlower part of the car supported on the upper part and springs interposedbetween the two parts of the car, all as substantially shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.
